Hi Pavel,

Thanks for the feedback.
> I think 12345678912345 is good enough. Underscore dividers make reading little bit easier but look weird overall. I can't remember other places where we output long numbers with dividers.
We already support this in SQL:
psql (18devel)
=# SELECT 123_456;
?column?
----------
123456

Best regards,
